PS1 games that have bugs in retropie

@dd-indeed So help me out here, the documentation seems to state the file name needs to be SCPH1001.BIN but it seems that by what you're saying, that could be a newer BIOS but just renamed to SCPH1001.BIN? Right now I'm sure my file is the original SCPH1001.BIN one and not a newer one. Any suggestions on which one to try or just go with the newest PSX BIOS I can find and rename it to SCPH1001.BIN?

@tropez You could try to find out your md5 value to compare what file you actually have to what is listed on this page: https://retropie.org.uk/docs/Playstation-1/

@tropez

I have the latest bios, that is from PSOne, and it's the SCPH101.BIN, missing one zero from it. And you need to get that, it's not enough, that you just use the SCPH1001 and remove that one zero out of it.

Is it just me or does the later PS1 titles have more issues than the older ones from the 90's ?

X-Com: UFO Defense will cycle the whole into then crash after that.
I tried with bin/cue, iso, mdf, and bpb file. Same behavior on the PC as well as the Rasp Pi. All files work without problem in another emulator. (epsxe)

@dd-indeed absolutely they do, systems and code were much simpler back then.

Someone else should try In Cold Blood. No matter what I try or what image I use, fps counters shows 60 fps all the time, but the game runs something like 20 fps.

hey @DD-Indeed please have a look at my post here you should deactivate an option to get fullspeed emulation.

which region? USA runs fine for me, you should try a different rom and verify the dump against the redump.org database.

emu: lr-pcsx-rearmed
BIOS: SCPH1001.BIN

Mine is the USA version and I dumped it straight from the disc. But then again, I tried this a long time ago, so it might have changed. I just stumbled into this thread today, so I tried to be helpful and I posted my comment.

no worries, thanks for posting. if you come across any more psx games with issues let us know so we can confirm/troubleshoot together.

My PS1 Experience so far on retropie 4.3 with raspberry pi 2

Bios: Filename is called "PSX - SCPH1001.bin" - it is in the Bios folder (is this the right bios and right file location?)

Games I've had issues with:
Metal Gear Solid - starts to load and I just get a black screen
Need for Speed III Hot Pursuit - Moves slow and becomes unplayable

Games that work:
Frogger
Mortal Kombat 4
Castlevania Symphony of the Night
Tekken 3
Madden 2000
Tony Hawk's Pro Skater 2

no. https://github.com/RetroPie/RetroPie-Setup/wiki/Playstation-1#bios

@dankcushions thanks for the reply, looks like I have to rename that file :)

@mtascavage

You should get newer bios as well, some games don't tend to work with that original bios from the very first Playstation version. :)

mtascavage

@dd-indeed I'll do that. Renaming the bios file correctly did resolve my Need for Speed and Metal Gear issues but cannot get Tomb Raider II to work. These were the games I bought and ripped myself and can play in a pc emulator. I'll try getting an updated bios

DD-Indeed

If you can get the PSOne bios (SCPH101.BIN, one zero missing), it is the latest one. Allthou, you also could try something like 55xx, 7xxx and 900x.
